What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Apnea testing is mandatory to confirm brain death; however, it is unsafe for patients who have substantial hypoxemia without ventilator support. We used a new modified apnea test without the need to disconnect the patient from the ventilator in the present study and compared the outcomes and complications of the new method to the widely used old method. Materials and Methods: The current study was conducted on people suspected of having brain death. Both the old and new apnea tests were carried out on the same individual. In the new modified method, instead of hyperventilating and then separating the brain death from the ventilator, the induced hypercapnia method was used, and instead of performing repeated arterial blood gas (ABG), the target ETCO Results: Thirty patients, including 25 (83.3%) males and 5 (16.75%) females, were included in the study. The results showed significant improvement in terms of O Conclusion: The modified apnea test produced better results in terms of O
